לְמַ֨עַן יִרְבּ֤וּ יְמֵיכֶם֙ וִימֵ֣י בְנֵיכֶ֔ם עַ֚ל הָֽאֲדָמָ֔ה אֲשֶׁ֨ר נִשְׁבַּ֧ע יְהוָ֛ה לַאֲבֹתֵיכֶ֖ם לָתֵ֣ת לָהֶ֑ם כִּימֵ֥י הַשָּׁמַ֖יִם עַל־הָאָֽרֶץ׃ (ס)
that your days may be multiplied, and the days of your children, upon the land which the LORD swore unto your fathers to give them, as the days of the heavens above the earth.
Targum Jonathan on Deuteronomy
that your days and the days of your children may be multiplied on the land which the Lord sware to your fathers to give you, as the number of the days that the heavens abide over the earth.
